## Questions & Answers

**Q: Will this fit my 2005 f 350 6.0**
A: Should do -- it fit my 2006 F250 6.0 -- A word of advice - make sure you use the install tool or you will destroy the seal during insertion. The tool is expensive (I recall around $80), but believe me you NEED the tool whether loaned or purchased. Best of luck.

**Q: This part did not fit my f250 06 . Wa to big for it**
A: Your truck has an 05 axle order the seal for an 05 it is smaller

**Q: Will this seal fit on a 2000 f250?**
A: This seal is for a 05 and up will not work on your truck.

**Q: The metal o- ring came out a part . Would it stell work?**
A: If the seal isn’t perfect I would buy a new seal. I bought the tool to install it and it went in perfect.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by M***R on April 12, 2025*

Haven’t used it yet but it looks well made

### ⭐⭐⭐⭐⭐ Read review for details.
*by S***O on August 20, 2020*

Have a 2008 F350 Lariat. Reviews said these were perfect. Every auto store website said these matched up right. They left about 3/16 gap from seal to axel seating. I thought I did something wrong or they were not the correct ones. Said screw it and put my axel back in. Kept popping off. So I took my old seal put it in there w these and beat it in. Actually worked perfectly. Along w the upgraded dust seal. Axel and dust seal has a small gap as well. But its sealed I promise. Both work great. Took some beating to get my pass side axel out and in. Driver side slipped out and in easy. Wire brush axel and knukcle before replacing. And spread some grease on everything.

### ⭐⭐⭐⭐⭐ Perfect Fit for 2011 F350
*by M***S on March 4, 2024*

This oil seal was a perfect fit for the front axle of my 2011 F350. It’s not fancy, but it did the job without issues.
